"Got any other immediate options besides fission reactors?"
Yes, try to get the total global use of electricity cut dramatically. I'm a Merkin, but the other countries blame us for using so much more power per capita than other countries. If more power is generated locally by solar energy, it will reduce the demand on the grid. And with more geothermal power the demand on the grid should also be reduced. If superconducting materials are used for long distance transmission, it may be possible to make a large enough grid to get power from the sunny side of the earth to the dark side. That should also help. Recycling more aluminum instead of using so much electricity to process ore will also reduce the demand. It's these incremental things that are going to have to help, and nuclear power is just another one of them.
I remember when an average TV used to use 350 watts of power; now they use more like 35 watts up to maybe a hundred. That's a big savings considering all the TVs that are running. Replacing equipment with newer, less power hungry versions will also help. One example is LED lighting. This benefits the user because the electric bill is less. If it requires that the turkey contractors are not allowed to install the older less efficient equipment (washers, dryers, and especially dishwashers) then get the laws passed to make it happen. Someday perhaps there will be no grid. Instead the homeowner will have a fuel cell that runs off fnatural gas and, along with solar, supplies all of their electricity needs.
Re: How much money is seriously spent on renewable research?
Some of the solar generating facilities here in California use mirrors to concentrate the sunlight onto pipes that have oil heated and circulated to the generators. The heated oil can also heat a heat storage facility, which is then used to run the generators after daylight. Also, some of the generators can run on both solar and fuel such as natural gas, which allows the generators to run during the dark hours. This is nor rocket science, it's here today. There is also geothermal power, which can run 24/7.
Solar photovoltaic panels can be added to existing buildings and put out peak power when the sun is brightest and hottest, and when the HVAC is working its hardest. This makes the peak demand on the generating and transmission system much lower, since it's synced with the peak demand.
I'm from the U.S. but...
So I don't really know anything about (or hear) DAB. But... My observation from digital TV is that the broadcasters want to squeeze more 'stations' (broadcasts) into a single channel, in order to maximize revenue, commercials I assume. So now the expensive 1080P TV doesn't get many stations higher than 720, and when I was watching one station and they showed a flock of birds taking off, the whole screen became blocky and pixellated, presumably because the compression algorithm couldn't handle the high rate of changed data caused by all the movement. Same thing with sports scenes or other action scenes. It sucks.
And every time I turn off the switch to the fluorescent light, I lose a half second of audio and video. I long for the days when all you'd see was a glitch on the screen and (probably not even) a click in the sound. I wonder if DAB is going to suffer the same vulnerability. In which case, I think it should stay away from the U.S.
What could be worse is if HPN or ethernet over the power lines starts to interfere with the DAB signals. Or if the 'white space' digital signals start getting too close to the DAB signals. Stuff happens...
Re: DAB Bashing
If most of the people in the 'neutral or positive' category are neutral, then what is the justification for changing it?
And if you already have FM sets all over the place and you're satisfied with the content...
If something isn't broke, then why fix it? Just my two U.S. cent's worth.
Oh, yeah, I forgot about one reason. Changing to DAB will help the manufacturers sell more radio sets. Obsolete all those FM sets and we'll sell all these DAB radios.
Oh, they forgot that the users could just change over to their favorite stations on their PCs, laptops and mobes -- for free. Duh.
Re: DAB Bashing
Perhaps someone will come up with a converter box that rebroadcasts a single channel on a FM frequency, over an area of a few tens or so square meters. Then the old FM radios will be able to receive any one of the DAB channels. Something like a mobile hot spot for FM radios. And if they wanted to add a feature, they could decode the online radio stations and rebroadcast one of them, too. It will probably put a dent in DAB set sales, so the manufacturers will probably oppose it.
Boo! Happy Halloween.
Re: Spin-off technology?
They may need to use this with silicon. When the dimensions get small enough to cause the defects to increase and the yields to go down, this may be a way of correcting the defects and rescuing the chips from the rejects bin. Just add a few spares here and there.
Re: How about .....
I find it amusing that so much trouble is go to just to harvest a fraction of a milliwatt. I have an inside/outside thermometer with LCD that has been running for much more than a decade on a single AAA cell. With an LR44 button cell, it should run for much more than a year. So it seems a waste to try to get energy from an unpredictable source when a button cell at a cost of a few cents does a much better job. Or take the design from the calculator industry. Just use a small solar cell and get a lot more energy than from a very intermittent microwave source.
Re: Could someone clarify bias "mixing" please?
When I said superimposed, I should have said that it was the same as mixing the audio with the AC bias. This was done at the head. But you could have thought of the AC bias as being just another audio signal mixed with the audio.
Of course the AC bias was more powerful than the audio because it had to overcome the hysteresis in the magnetization. Also the same AC bias was used to erase the tape.
Re: Could someone clarify bias "mixing" please?
I like to think of it this way. The tape is magnetized positively and negatively (or plus and minus) many times by the bias during the time a point on the tape passes over the gap in the head. On the average, the magnetization is zero because the bias signal is an AC sine wave, with no DC component. As the audio is superimposed onto the bias, which looks to the head gap like a slowly varying offset in the bias magnetization, the audio causes that average to go positive and negative, and so the average magnetization varies with the audio signal. This is what is left on the tape. And the bias changes polarity so many times during the time the tape is in the gap that there is no bias frequency on the tape. What you hear is just the audio.
Some very cheap tape recorders used a magnet to give the tape head the 'DC' bias, instead of the AC bias signal. Magnets were also used to erase the tape. But the AC bias gave a much better erasure.
I think they've bitten off more than they can chew. ;-)
I constantly see these "Lose weight by doing this One Easy Trick" type of ads. They're like a magician: you know there's gotta be a catch to it, and your curiosity gets the better of you, so you fall for the bait. Sure these spammers generate content, and they do it by stretching the truth until it is so thin it's totally transparent. Legit companies don't need to go to all the machinations of trying to get the suckers to fall for their products. If the same method was used to sell a legit product, the spammers would be branded as scammers. P. T. Barnum was right.
Point Taken - Re: This kind of attitude is wrong
I wonder if anything can be read between the lines of "tightening up (our whatever)". Like I just got chewed out by the Boss because I let this slip through without catching it the first time.
Maybe the fear of being fired will instill a bit of diligence into them and prevent it from happening again.
But talk about misspelling:
"And can you please invent you own language instead of misspelling ours?"
We have a Scotsman named Alistair, and it's such an improvement to listen to him, compared to the British accents at the "pub" down the street.
I Second That Emotion!!
Just like the word soccer, it wasn't us Americans that came up with that system of measurement., it was the British. Just be glad it isn't expressed in furlongs!
Re: America "..In very dire straits indeed."
Manning went to prison as much for being in the military as he did for his actions. When you are a member of the U.S. military, you sign away many of your rights that you would have had as a citizen. He was punished under the UCMJ (Uniform Code of Military Justice), NOT the U.S. constitution.
Horrible inefficient? - Re: Freeview vs cable
Inefficient in what way? The amount of power in ERP is much greater than the actual power output of the final power amplifiers of the transmitter because of the very high gain of modern antennas.
Also consider that there is no cost for installation of cable, fiber or copper, just set up a transceiver and maybe a small antenna. Google is planning (or already doing) the high altitude blimps for terreestrial WiFi coverage
Re: What have the Romans ever done for us? @AC 12:32
They gave us the cobblestone roads all over Europe, and the ruts in them, too, from the chariots.
I remember forgetting this stuff....
HUH? How could you remember forgetting it if you forgot it to begin with?????
Re: "When I mentioned a taxi as a good alternative, they said, "No, were used to drinking and driving, you're not, so that's why you need the cab"."
Nah. He just couldn't cope with driving on the "wrong" side of the road. Loaded OR sober.
<<It was only mildly on fire.>>
Well, DUH! When an airplane is made out of plastic (carbon fiber composite), there's no such thing as MILDLY!
One other point... I thought that the protocols used in these bands were spread spectrum, frequency hopping, etc. So if there's a frequency in use, the equipment just skips using that frequency and goes about its business with little or no bad effects. In other words, there is no need to "kick out" one type of user, since they're all interfering with one another on an ongoing basis. Sort of like a free-for-all.
Gimme, Gimme, Gimme...
I don't know about the U.K., but the U.S. feds forbid radio amateurs from using the ham bands for commercial purposes. So if these bands were to be "monetized" (seems like a new term - thanks, Google), then it would be unfair to expect the radio amateurs to pay for something for which they could never recover their costs.
"... like Apple have taken a bigger role in servicing customers."
Servicing... Like a bull services a cow.
In another article they talked about a 10 Euro E-reader. With those kinds of prices, it looks like paper is dead. Maybe the politicians will get enough lobbying from the paper industry to put a tax on e-readers, to help pay for the recycling.
One point about using paper for anything electronic... Paper is not a good insulator, and absorbs humidity, which makes it conduct electricity. That's one problem that has to be solved before it can be used for a printed circuit board substitute.
One Would Think...
That by now, 99.99 percent of these "gaping holes" would have been fixed, and we would not need to have a patch Tue every single month. But if people keep converting over to tablets, we will fix that problem, eventually. Except for my organization, which has given me a Win 8 desktop with a touch screen. Which sits back against the wall, and seldom gets touched. DUH.
Re: Alan Turing
In this article there was a statement made about Turing that I believe is incomplete, incorrect, or both. If you have any interest in Turing i suggest you read his bio or Wikipedia or some other more factual source.
Other than that, I thought the article was good, and I agree with the other principles it discussed.
I would just go to Harbor Freight Tools and buy a cheapo generator, or else rent one for the temporary job. Then set it outside and fire it up, and remember to keep a can of gas (petrol) handy when it gets low. A few longer extension cords should complete the installation. Just remember to roll them back and stow them up so the local thieves don't steal them for copper.
Or if you have a bit if money, put solar water heating panels on the roof. Or maybe use the exhaust heat to heat the water.
It's the Apps, Stupid!
People don't care about what operating system the thingy uses, all they want to do is get a job done, and be able to share what they do with others. if there's an app on iTunes or marketplace that does it, then they're happy. Corporate will succumb to this too, as soon as they realize that they can do it, too.
Re: An exception to the rule - with some help.
I had the same experience with my credit union. It took them a few times, but they finally got to the bottom of the problem and fixed it. I dealt by email with not some flunky, but the VP.
I went to Office Depot and as I checked out, the cashier asked, "Do you want your receipt as paper or by email?" BINGO!!! As soon as they get your email address, the spam starts rolling in!! Of course, I told her, I'll take paper, 'cause if I give you my email address, you will spam me! And I already have enough of that.
Re: Remember the rumors that Stuxnet was written by the US military, CIA, etc.?
From what little I remember about Ada when I took the class, was that it was not a compiler, not an interpreter, but a translator, which spit out FORTRAN on the IBM 4361. What a joke. One Ada run took 8 minutes to complete and if more than one was running, it was more like 20 minutes.
I was going to speculate before I read the article. Then I thought, if it's really that obscure, those spooks just want to know if anyone has knowledge about it, so they can interrogate^H^H^H^H^H^H^H^H^H^H question the person about whether or not they had anything to do with writing the actual code (!)
I and other Californians are not really holding our breath for any windfalls. In the intervening time, with gasoline prices here already over $4, going on $5, we are more likely as not to see whatever windfall wiped out by higher food, transportation and other costs. Someone ought to throttle the Wall St. bunch who speculate on the price of crude.
The crooked colluders here in California charge us an additional tax on any LCD screen bigger than (I forgot) inches "for disposal". I could see this with the leaded glass in CRTs, but why are we getting screwed with lead free LCDs?
It's not minor when the number of spams he's spewed has more than nine zeros at the end. If you want proof of what I said, you can go back to the journals and see from the number of lawsuits he's lost and hundreds of millions of dollars he owes that this BSFH is in no way, shape, or form a minor spammer. He wasn't given the name King of spam for no reason.
And here's another fact: if you took all the electricity this BSFH has caused to be wasted on spam and put it on the electric grid, it could power the whole world for a year, if not a decade.
I learned well from my mother, who told me "I told you a million times not to exaggerate!"
It's about time they throw this recidivist in jail. Please? Just throw the key away. Just conveniently lose it - you will be doing the whole world a very big favor. Actually they should give him a video screen. One with an infinite number of channels, each channel only displaying one of his spams. That should (almost) be enough punishment.
And when he dies, he will suffer eternal damnation for being the worst human being in this world for causing the most hatred.
The second and third worst are Canter and Siegel.
I think it may be a good idea to send the email with only a link to the information, with a 'shrink wrap' statement that by clicking on the link, the recipient agrees to abide by the laws of <insert non-German country>, etc. Also the linked info should obviously not be on a server in Germany.
The following paragraph (I quote) has some discrepancies, it's misleading at least:
"Almost all other infrastructure hit by the natural disaster failed catastrophically. Housing, transport and industry across the region collapsed with deadly consequences, killing people by the tens of thousands."
The housing, etc., didn't collapse, it was washed away by the tsunami.
This incident did the most damage to peoples' perception of nuclear power. It showed that even though the Japanese knew historically about tsunamis as bad as this one (in 869 and 1896), they failed to design the barriers to block waves the height of those historic tsunamis. They chose to save money and as a consequence the plant was damaged by their cost cutting measures, instead of by mother nature.
After that, can you convince anyone in their right mind, especially insurance companies, to allow or insure a design that is potentially flawed? I think not.
Unintentional vs. Intentional Radiators
Here in the U.S. the Part 15 mentions unintentional and intentional radiators. Well, if you have a motor, printer or other similar device radiates interference, it was not meant to do so and the interference is unintentional. It can also be mitigated by filtering with EMI suppressor sleeves on the cables, for example. These are the black bulges on the ends of the cable.
But now you have this power line ethernet device where the whole design is centered around the transmission (and incidental radiation) of high frequency energy over bare wires. If that isn't intentional, I don't know what is. If you try to get rid of it by filtering it out., the whole system stops working. In other words, the system is built in such as way as to purposely interfere with other nearby equipment.
I saw these were now available at the Microcenter store in their ads last week. FIrst off, I would never put one in service on my premises, because of the interference. Second, has anyone looked into the security of these signals? Can just anyone decode the radiated signals and find your private information? I would never trust them because of this risk.
Another problem that can happen with commercial installations where three phase power is used is that the sending equipment is on one phase, and the receiving equipment on another phase. So you end up with spotty or no communication.
Just use WiFi, or regular cat5 wiring. Just say NO to this junk.
I'm suspicious of this.
I'm suspicious of this. What puzzles me is why the FBI's crack team of specialists in this field would not be able to solve something a high school dropout made up. Maybe the FBI is trying to get under cover cryptanalysts to come out, so they can secretly monitor their life to see if they're working for a foreign government.
Or maybe they'll offer the amateur cryptanalyst a job...
Doesn't Change Reality
I think Page's perspective is interesting, but that doesn't change reality. For instance, the four nuclear power plants at the Fukushima Daiichi site, even if tamed and made safe, are likely to never come back online. The bad publicity has done a tremendous amount of damage to the nuclear power plant industry's reputation, not to mention the many hundreds of millions of dollars it will cost to replace the four plants.
New Mexico? I don't think so
According to Mojave Spaceport, they're not in New Mexico, but in California:
But, But, But...
The Analytical Engine should not be built UNTIL it has been 'built' in virtual reality. With the power of today's computers, it will be possible to do exactly the same thing, and also be able to take a virtual tour of the insides of the machine, much more intimate than the 'real thing'. And if the simulation is open source, anyone can d/l and run it at their own convenience.
But today's (Tue 9-7 Doodle is even more fun!
It makes my task manager performance graph kick up to 50% or so. But it's COOL!
Probably about a snowball's chance in hell of collecting it. But the punishment should be appropriate to the crime, which is it not. The spammers generate 90 percent of all emails, and should have to pay 90 percent of all email servers and email bandwidth used by the ISPs. Then maybe the SOBs would almost get their just punishment. Unfortunately there is no punishment for the amount of aggravation and consternation the users suffer.
If I remember Correctly...
The end product of a nuclear reaction still has radioactive nuclides in the spent fuel, so it's still a problem after the end of its life. Besides, any company (at least in the U.S.,) that makes these will not be able to get insurance nor funding, so it's doubtful that anything like this will ever get built.
Maybe they could just tow an old nuclear submarine up to the dock and plug it into the power grid. If anyone asks, just tell 'em it's charging its batteries. ;-)
I took two semesters of Photoshop 4.0 back in '98 and 99, for what it's worth, and I learned to use only a tenth of it, at that time. It is a program with a very complex set of features. I'm sure there are people out there who use more, but I can get most of what I need done with some silly free program nowadays.
Back in the early '90s for awhile I used a some program from a student in the technical university of Taiwan, it might have been called Display. It was free, and didn't do much manipulation but ran okay under DOS.
BTW, the Macs in the classroom crashed just as often as the Wintel machines!
